The HTG3500 Series is a humidity and temperature plug and play transducer designed for OEM applications where reliable and accurate measurements are needed, based on the rugged MEAS-France humidity sensor.
The HTG3500 Series are plug‑and‑play humidity and temperature transducers designed for OEM applications that require reliable, accurate measurements. They feature a rugged MEAS‑France humidity sensor, linear voltage output for humidity and a direct NTC output for temperature, and are optimized for low power consumption.
The modules support 3.3 V or 5 V supply options, operate over a wide temperature range, and include mechanical features such as screw‑mountable or PTFE‑membrane housings. They are qualified for harsh environments, offering protection against EMC, reverse polarity, and a variety of chemicals.
